Hi,

        I am sure that you have heard about battery powered cars and perhaps even hydrogen powered cars. Now there is a compressed air car. It uses a motor powered by compressed air, and can be operated on both gasoline and compressed air or just compressed air. A compressed air engine works by expanding compressed air.

Engines can  operate with pistons or turbines. These engines can improve performance by heating the compressed air. The present engine and car has been developed by a frenchman although compressed air engines have been around in different forms for many years.
